Siena,
i need your advice as regards my 3.2l vr6 touareg, i recently changed one of the post cat oxygen sensors in a bid
to correct the permanently illuminated CEL,unfortunately, the light is still on and i ran a scan again just to realise that the second post cat lambda sensor needs to be changed.
After series of maintenance checks were warried out, i realised that the tranny sump had a wet patch, which indicates that the gasket is probably torn and needs to be changed, this is most likely responsible for the harsh downshifts ive been experiencing from D5 toD4.
In this regard, im wondering if u could help procure the replacement gasket,o2 sensor,aisin recommended tranny oil.
Also, a detailed expalnation of how to carry out the tranny oil change will be highly appreciated.
Thanks a zillion

*Remove underbody panel. Remove metal brace that rear section of underbody panel attaches to.
* Drain fluid via torx drain plug.
* Remove pan and gasket.
*Replace filter, don't forget the black o-ring!!! torque to 7.5 ft-lb
*Clean pan, fit new gasket. re-install pan. Torque the bolts to 4.5 ft-lb
* Install drain plug, 21 ft-lb
*Remove hex head fill plug. We have a special tool for filling the trans. Good luck with this. Maybe you could use one of the generic pumps you can get at Napa, etc. Fill trans until fluid spills out of hole. Re-fit hex head plug.
*Now this is were the we use the PIWIS, you must set the level with the transmission at 40 C. Maybe use a infared heat gun
* Warm up transmission in lower load range. Switch all transmission ranges several times while doing so. (P,R,N,D 2nd and 1st)
*Read out ATF temperature using the PIWIS Tester. ATF temperature: 40 °C.
*Selector lever is in position P.
*Test and filling process at idle speed.
* Fill trans. until fluid overflows hole.
*Torque fill plug to 52 ft-lb
* Filling capacity is 8.5Liters or 9.6Liters pending on trans. build date.

Compliments of the season to you,

Please i need your expertise knowledge to diagnose the problems i have seen with my Audi car.

Audi
A4
V4
Manual transmission of 5 speed
The year am not sured of.
It is US or Euro
Front wheel,

The car is always difficult to start when cold or hot (when parked for a short while). Also the car jerks in motion. the airbag light is always on while the handbrake light on the dashboard comes up intermittently.

Mr. Siena, what are the possible causes of these problems highlighted. Sir, your speedy response is highly looked up to. The car is going bad each day. you can reach me on: abbeybj2002@yahoo.com

Mr Siena,
Please could you describe the location of the hexagonal head fill plug?
I cant locate it .
Thanks so much

SMOOOTH:

Thanks siena !

So now that i have a well documented DIY procedure, whats d next step as per procuring d  replacement parts?

As per your request, what came up after the scan was something like this:

P301 O2s ckt no activity 2 of 1
It baffles me , cos i dont know what that means.

I hope the description makes sense?

Sienna ,

Just an update , ive been able to set my hands on a torque wrench , a fliter belt, my challenge is how to use d filter belt to get a torque of 7.5pounds/feet or maybe the filter is tightened using attached bolts? i guess i will find out by the time i carry out disassembly

im still trying to look for an infra red heat gun and a generic pump,

Rather than jack it up, i could carry out the job by working from a pit the type found in filling stations in nigeria?

still waiting on the cost of :

1 post catalytic converter lambda sensor

1 tranny oil filter

1 tranny sump gasket

10ltrs of aisin recommended tranny oil.

Thanks !

It's good to see one tackling jobs on their vehicle themselves, it gives a great feeling of achievement.

Two items here are chassis number dependent. There are 6 different part numbers for the Aisin fluid, and getting the wrong one will be a major pain. The post-catalyst O2 / Lambda Sond has 4 part numbers too.

If you could post the VIN, that will enable me get the correct items, without any guesswork.

Hi Siena, I salute u for the great job u are doing here. I just wanted to know if Volkswagen Tiguan is a good choice. Ve deposited some money for it. I'm buying and shipping from America, so it's American specs. There is this premium oil issue I read about it. Pls advise as it is not too late. Thank you.

I forgot to mention the engine. It's a 2.0turbocharged engine
